に結露水の発生が問題となつていた。 In the case of external walls of buildings and structures, for example, when cement mortar walls develop over a wide range of cracks and peeling due to aging, the external walls must be removed and reapplied. This work required many days and man-hours and had the disadvantage of damaging the pillars and base plate. In addition, during the construction period, tents,
It was necessary to carry out other temporary construction work, which increased costs, and in severe cases, there were disadvantages such as having to cancel the residence. Furthermore, in order to save energy, conventional exterior walls lacked a heat-insulating structure, making them less comfortable to live in, and they also had drawbacks such as high heating and cooling costs. Moreover, when applying this type of heat insulation structure to a conventional outer wall, a method is known in which the space between the inner wall and the outer wall is filled with a heat insulating material. However, in this case, the entire wall would have to be demolished,
It requires a considerable amount of cost and man-hours, and because the mortar wall itself is breathable, it has the disadvantage of deteriorating the insulation material and causing dew condensation. Additionally, mortar walls have uneven surfaces, so if a rigid exterior material is directly applied, the decorative surface of the new wall will be adversely affected by the base material, resulting in an unsightly appearance. Furthermore, when conventional exterior materials were installed, there was a problem of condensation water forming on the back side of the joints.

を示すものである。 An embodiment of the exterior wall repair method according to the present invention will be described in detail below with reference to the drawings. Fig. 1 shows an external wall formed by the external wall repair method according to the present invention, and 1 is an existing external wall, for example, a cement mortar wall, with a cement mortar layer 2, a lath 3, a waterproof layer 4, a lath board 5, and a main wall. It is composed of a main body 6 of a pillar or stud. Reference numeral 7 is a base material that functions as a heat insulating board, a base material, a cushioning material, a reinforcing material and a moisture barrier layer, or a moisture absorbing material.As shown in Figure 2, its structure consists of a hard base material 8, a heat insulating material 9, and a material pasted on the back side. It is a plate body that is an integral composite of a sheet-like material 10 attached to the surface of the hard base material 8 and a waterproof sheet 11 attached to the surface of the hard base material 8,
Its standard size is approximately 20 to 50 mm (thickness H) x 900 mm (width W) x 1800 mm (length L). Of course, it goes without saying that the size is not limited to this size. To explain further, the hard base material 8 of the base material 7 mainly functions as a reinforcing material, and specific examples thereof include plywood such as plywood, gypsum board, wood wool cement board, slate board, etc. It is what it is. Further, the heat insulating material 9 is made of synthetic resin foam, and it is desirable that this foam has compressibility of at least about 0.5 to 3 mm. Specific examples include polyurethane foam (soft and hard), polyisocyanurate foam, polystyrene foam, phenol foam, urea foam, polyethylene foam, and vinyl chloride foam. In addition, in order to integrate the hard base material 8 and the heat insulating material 9, it is possible to integrate the hard base material 8 with an adhesive, or to discharge the raw material of the heat insulating material 9 in an on-site foaming manner and utilize its self-adhesive property. The synthetic resin foam layer may be formed simultaneously with the formation of the synthetic resin foam layer. Note that the heat insulating material 9 covers the surface of the hard base material 8,
Or provide it so that it completely covers the back side. Also,
The sheet-like material 10 mainly has the function of preventing loads from being applied to the extreme parts of the waterproofing material, moisture absorbing material, and heat insulating material. Further, the sheet-like material 10 is a heat insulating material 9
In addition to protecting the base material 7, its strength is further improved by forming the base material 7 into a sandwich structure. Moreover,
Secondary functions include at least one function such as waterproofing (including non-permeable), preventing dew condensation through water absorption, and improving heat insulation through heat radiation.
The sheet-like material 10 is made of asphalt felt, tar felt, kraft paper, asbestos paper, or laminated with one or more of synthetic resin film, metal foil, etc. (which also has a radiation effect). Or, if necessary, it can be waterproofed. Reference numeral 11 denotes a waterproof sheet, which is larger in size than the hard base material 8 and has a polymeric piece 11a with two adjacent sides protruding by Δl, and can be attached to the hard base material 8, fixed with staples, etc. It is installed in one piece. In particular, the polymeric pieces 11a cover the joints when the base material 7 is fixed on the existing exterior wall 1, and prevent rainwater from leaking into the interior, as well as waterproofing the joints of the siding material 12, which will be described later. It also helps prevent condensation. The base material 7 is fixed to the existing outer wall 1 using fixing tools A such as nails and screws.
The sheet-like material 10 is fixed by coming into contact with the existing outer wall 1 via. In this case, 3.03 m 2 is covered with two base materials 7. Unlike the so-called base of conventional lath board, it is highly efficient in construction.
Reference numeral 12 denotes a siding material made of either metal or ceramic material, and its structure is that in a metal siding material, a surface material 13 made of a thin metal plate is filled with a core material 14, and the back surface of the core material 14 is filled with a core material 14. A sheet-like material 15 is stretched or pasted. To explain further, the surface material 13 is formed from a male connecting portion 16, a female connecting portion 17, a decorative surface 18, and the like. The core material 14 may be made of synthetic resin foam (for example, polyurethane foam, polyisocyanurate foam, phenol foam, epoxy foam, polyethylene foam, or a foam obtained by adding perlite, borax, etc. to these foams), rock wool, cellulose-based heat insulating material, or glass wool. No. 1
It consists of seeds. The sheet-like material 10 is made of one of moisture-controlling kraft paper, cardboard, waterproof asphalt felt, and synthetic resin film. Note that the specific shapes are for metal-based siding materials as shown in FIGS. 3a to 3j and ceramic-based siding materials as shown in FIG. 3j.

性能差が顕著に解るものである。 Next, to explain the exterior wall repair method according to the present invention, first, a new exterior wall B with a cross section as shown in FIG.
It is assumed that the base material 7 shown in FIG. 2 and the metal siding material shown in FIG. 3a are used in order to form this on the existing outer wall 1 consisting of a mortar wall. The cement mortar layer 2 of the existing exterior wall 1 is 25 mm thick, the base material 7 is 21 mm thick, the hard base material 8 is 9 mm plywood, and the insulation material 10 is polyurethane foam with a density of 30 Kg/m 3 and 16 mm thick, and siding. The material 12 is the product name, Makabe (the surface material 13 is a 0.27mm thick color steel plate,
It is assumed that the core material 14 is a polyurethane foam having the same specifications as above, and the sheet material 15 is made of kraft paper laminated with aluminum foil and has a sandwich structure with a total thickness of 15 mm (manufactured by IG Industries Co., Ltd.). Therefore, the sheet-like material 10 of the base material 7 is laid and fixed in contact with the existing outer wall 1, and fixed using the fixing tool A. In particular, the reason why the sheet-like material 10 is brought into contact with the existing outer wall 1 is to prevent the penetration of indoor and outdoor air and moisture, and to suppress shock and vibration from the existing outer wall 1 by the cushioning properties of the heat insulating material 9. This functions to make the decorative surface of the new exterior wall B flat. Next, a siding material 1 is applied to the surface of the base material 7, a waterproof sheet 11 on the so-called hard base material 8 side.
2 is fixed vertically to the main body 6 of the existing outer wall 1 via fixtures A to form a new outer wall B. Therefore, when comparing the heat transmission coefficient between this existing outer wall 1 and a wall in which a new outer wall B is formed using this existing outer wall 1 as a base, the former is 0.02 kcal/m 2 h°C, while the latter is 0.54 kcal/m 2 h°C. m 2 h°C, and the difference in insulation performance can be clearly seen.
